Abstract
The present invention relates to a seeding device in agricultural machinery. The invention provides a seed metering device suitable for small-sized seed precise and small-amount sowing. The device can be used for sowing seeds in a line in sequence. The device consists of a seed charging box, a seed limiting baffle plate, a seed discharging baffle plate, a seed charging groove, seed cleaning sheets, a hairbrush and a seed cleaning gap. The seed charging groove is an annular groove and can arrange seeds into a line; the seed limiting partition plate limits the amount of seeds above the seed filling groove, so that the extrusion force borne by the seeds is reduced, and the seed injury rate of the seeds is reduced; the seed discharge blocking piece is lower, and the seed is easier to fill; the damage to the seeds is reduced by adopting a hairbrush; a gap is reserved between the brush and the seed discharge baffle plate, so that the shearing force borne by the seeds is reduced; seed cleaning avoids the seed from being blocked in the seed filling groove to form miss seeding.
Description
Technical field
The present invention relates to the seeding apparatus in agricultural machinery.
Background technology
Seed can be reasonably arranged in precision drilling, reaches saving seed, rationally utilizes soil fertility, sunlight and wind-force, obtains good procreation enviroment, coordinates individual and group relation, realizes the percentage of earbearing tiller high, and individual plant fringe is many, grain is many, full, thereby reaches the object of high yield.Precision Seeding culture technique only could put into practice in large area by means of the sower of function admirable.Precision drilling machineryization technology has the advantages such as province's kind, saving of labor, energy-conservation, high yield.Wheat is one of China's staple food crop.The wheat cultivation amount of broadcasting is large, spacing in the rows is little, and existing Wheat Precision Metering Device is owing to filling the restriction of kind of time, and speed of drilling is low, and percentage of damage is higher, and the conventional seeding unit of wheat seeder is fluted-roller feed mechanism now.But due to the structure of fluted-roller feed mechanism, in the time that seeding quantity is less, seed flow is pulsation phenomenon, and uniformity is affected.Therefore, design a kind of mechanical seed sowing device of applicable small-sized seed defective ejaculation amount sowing, plant and be significant for raising seeding uniformity, volume increase, province.This mechanical type dispenser is applicable to broadcasting the small-sized seed of similar wheat, Chinese sorghum, millet (hybridization millet) etc.
Summary of the invention
The invention provides a kind of dispenser of applicable small-sized seed defective ejaculation amount sowing.This device can be arranged seed and into a linely sow successively.This device by filling kind of a box, limit kind of dividing plate, a seeding catch, fill kind of a groove, seed cleaning sheet, hairbrush and plant clearly gap and form.
The technical solution adopted for the present invention to solve the technical problems is: kind of a grain weight for groove top is filled in the limit kind dividing plate restriction of filling in kind of box; Filling kind of groove is a cannelure, and cross section is circular arc or trapezoidal; Fill in kind of groove, be uniform-distribution with seeding catch, the high 1/2-1 of seeding catch times seed width, fills the high 1-3/2 of kind of groove times seed width, seeding catch top with fill kind of groove top and have the gap of 1/4-3/4 times of seed width; Hairbrush stops and fills seed outside kind of groove and discharge seeding unit, hairbrush with fill kind of a groove top and join, gap and the seeding catch top between hairbrush and seeding catch top and to fill gap between kind of groove top identical; Filling kind of a trench bottom has a narrow annular channel, for the clear gap of planting, plants clearly gap through seeding catch; Seed cleaning sheet fills kind of groove through filling kind of groove arrival in clear kind of gap, will fill seed derivation in kind of groove and fill kind of a groove.
The invention has the beneficial effects as follows: filling kind of groove is a cannelure, seed can be arranged into a line; Kind of a grain weight for groove top is filled in limit kind of a dividing plate restriction, reduces the suffered extruding force of seed, reduces seed seedling-damaging rate; Seeding catch is lower, more easily fills kind; Adopt hairbrush to reduce the damage to seed; Hairbrush and seeding catch are gapped, reduce the suffered shearing force of seed; Seed cleaning sheet avoids seed to be stuck in filling forming in kind of groove broadcast leakage.
Brief description of the drawings
Below in conjunction with accompanying drawing and example, the present invention is further described.
Accompanying drawing 1 is structure chart of the present invention; Fig. 2 is installation diagram.
In Fig. 1,1 fills kind of box 2 limit kind of dividing plate 3 seeding catch 4 and fills kind of the groove 5 seed cleaning sheet 6 clear gaps of planting of hairbrush 7.
embodiment
Fill in the accompanying drawings the interior part seed of kind of a box (1) owing to being subject to the effect of gravity, make seed arrive hairbrush (6) and be filled with before kind of a groove (4); Limit kind of a dividing plate (2) is controlled and is filled the interior seed pressure of kind of a groove (4); Fill seed in kind of a groove (4) and rotate with filling kind of a groove (4), arrive hairbrush (6) and locate, fill seed in kind of a groove (4) under the thrust of seeding catch (3), with filling kind of a groove (4) by hairbrush (6); Do not enter the seed that fills kind of a groove (4) completely, due to the thrust of seeding catch (3) not and the resistance of hairbrush (6), seed is by the gap between seeding catch (3) and hairbrush (6) bottom or slip into filling in kind of a groove (4) below, or skids off and fill kind of a groove (4); Seed by hairbrush (6) is derived and is filled kind of a groove (4) and sow by planting clearly seed cleaning sheet (5) in gap (7), and seeding operation completes.
Claims (3)
1. the dispenser of an applicable small-sized seed defective ejaculation amount sowing, this device by filling kind of a box, limit kind of dividing plate, a seeding catch, fill kind of a groove, seed cleaning sheet, hairbrush and plant clearly gap and form, it is characterized in that: filling kind of groove is a cannelure, cross section is circular arc or trapezoidal, and filling kind of a trench bottom has a narrow annular channel.
2. the dispenser of a kind of applicable small-sized seed defective ejaculation amount sowing according to claim 1, is characterized in that: fill in kind of groove, be uniform-distribution with seeding catch.
3. the dispenser of a kind of applicable small-sized seed defective ejaculation amount sowing according to claim 1, it is characterized in that: the high 1/2-1 of seeding catch times seed width, fill the high 1-3/2 of kind of groove times seed width, seeding catch top with fill kind of groove top and have the gap of 1/4-3/4 times of seed width.
